Comp cams xe268h for 318

With what stall? and gear?
This why the factory put 2400s and 3.23s behind them.
BTW, the factory cam was also a 268; but worse is, it was a 268/276/114 with valve events of : intake 22/66 and exhaust 74/22 Which sucks the pressure down further than a 268/276/110, given the same real starting points. The factory cam shoulddabin even a lil softer out of the gate; I'm guessing 5psi less at cranking speed.
But I totally get the softness.
Yet guys with 7.8 teeners rave on that cam. There is ZERO chance I would ever put a 268 in a 7.8 teener for street use. You are exactly right, it would require a hi-stall and minimum 3.55s, to be remotely effective and fun.And with those it's pretty much a Citycar.
>>Now a 340 has a few cubes on the teener to help it off the line, but it still likes it's pressure, especially with a 114 LSA. Installed straight up, the 114 cam loses 4* of compression; 114 versus 118, changing the Ica from 62 on the 110 to 66 on the 114. To make the same pressure as the 110 cam, one would have to advance the 114 those missing 4 degrees...... which would, relatively speaking, kill the overlap period, and the absolute power along with it
Never mind that these two cams from different manufacturers are not directly comparable anyway. The Comp shouldabin better in every way, shoulddabin.
>>Spec wise; the Comp should make more cylinder pressure, more low-rpm power,more midrange, more top-end with a higher shift-rpm, and better fuel economy; and with headers, a nice little power boost at the top. It Shouldabin better.
